Positive Exponents 536D7A

1. **State the problem:** Simplify the given expression and write the answer with positive exponents only. 2. **Recall the rule for negative exponents:** For any nonzero number $a$ and integer $n$, $a^{-n} = \frac{1}{a^n}$. 3. **Apply the rule:** Convert all negative exponents to positive by moving the base with the negative exponent to the opposite part of the fraction (numerator to denominator or vice versa). 4. **Simplify the expression:** Combine like terms and simplify any fractions if possible. 5. **Final answer:** The expression is rewritten with only positive exponents. (Note: Since the original expression was not provided, this is the general method to simplify and write with positive exponents.)
